摘　　要：对2022年全球火山监测信息进行统计,2022年全球共有31个国家129座火山记录到火山喷发活动。依据火山预警等级(Ⅰ~Ⅳ)分类,统计了2022年度不同火山预警等级的数量及占比,分析了全球火山喷发活动水平,简述了6次全球典型火山喷发事件的灾害特征。根据2022年度火山喷发柱大于10 km的天数、火山喷发柱最大高度等统计结果,探讨了火山活动产生的火山灰及气体排放对全球气候的影响。The global volcano monitoring information for 2022 was counted,and a total of 129 volcanoes in 31 countries recorded volcanic eruption activities in 2022.Based on the classification of volcano warning lev⁃els(Ⅰ-Ⅳ),the number and proportion of different volcano warning levels in 2022 were counted,the global volcanic eruption activity levels were analysed,and the hazard characteristics of six typical global volcanic eruption events were briefly described.The impact of volcanic ash and gas emissions from volcanic activity on global climate is discussed based on the number of days with volcanic eruption columns larger than 10 km and the maximum height of volcanic eruption columns in 2022.
